@Adriana Gomez Thanks for posting in our Q&A.
To avoid any misunderstanding, we appreciate your help to clear something:
1.Which app type did you use to deploy this app?
2.Based on my understanding, app's package name must be globally unique in Google Play (not just unique within your enterprise or Google Play Developer account), when publishing an app in google play.
If this app is published, we can select this app in google play and sync this app to intune.
If there is anything update, feel free to let us know.
